F'IREPROOF CONSTRUGTION.

SPECIFICATION forming part of Letters Patent No. 662,635, dated November 27, 1900.

Application filed May 9, 1900. Serial No. 16,002, (No model.)

T0 all whom it may con/cern:

Be it known that I, WILLIAM WHITE, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Fireproof Construction, which improvement is fully set forth in the following specification and accompanying Y drawings.

My invention consists of an improvement in arch blocks for iireproof construction, whereby a protection is afforded for the iron and steel beams or structure to which they are applied and means furnished for supporting the concrete or cement to provide a strong and durable structure.

Figure l represent-s a perspective view of an archblock constructed in accordance with my invention. Fig. 2 represents an end view of two of the arch-blocks embedded in the cement or con crete, the same being taken on the line no, Fig. 3. Fig. 3 represents a vertical section taken on the line y y, Fig. 2. represents a perspective view of a modiiied construction embodying my invention. Fig. 5 represents an end View of two of said archblocks, the saine being taken on the line .a a, Fig. 6. Fig. 6 represents a vertical section taken on the line w w, Fig. 5. i

Similar letters of reference indicate corresponding parts in the figures.

Referring now to Figs. 1 to 3, A designates the arch-block, the same consisting of the upper curved side B and base O. Said upper side and base are joined by a plurality of upright walls or partitions D, whereby the requisite strength is imparted wit-hout unduly increasing the weight of the arch-block. At one end of the arch-block the base O is iiush with the end of the wall D and an upright groove or keyway E extends longitudinally through the central wall or partition,which is conveniently wider than the other partitions or walls D,said keyway receiving the key E to bind the archblocksagainstlateraldisplacement. Extending transversely across the end of the archblock at the upper end of the curved side B is a transverse groove F, which in conjunction with the corresponding groove of a cornpanion arch-block forms a keyway to receive a key Q, that extends through a plurality of Fig. 4.-

arch-blocks and produces an effectual bond. At the other end of the arch-block the base O is provided with a projecting flange G-, above which is the end shoulder or overhanging flange H, between which and said flange G is a chamber or space adapted to contain lling or concrete material, which covers the under side of the base of the I-beam M. The length of the flange H is less than that of the flange G for a purpose hereinafter referred to. At the sides of the arch-block the curved side B is provided with the overhanging flanges J, While the base O is provided with the laterally-extending lianges K of greater length than said overhanging fianges J. In the application of myinvention the said arch-blocks are applied to the I-bea1ns M, as shown in Fig.

3, the overhanging flange H resting upon the flanges of the I-beam and the ends of the iianges G meeting the corresponding flange of an adjacent arch-block midway below the I-beam M. The distance between the flanges G and I-I is greater than the width of the flange of the I-beam, so that a space is formed below the I-beam and the upper bases of the flanges G, as seen in Fig. 3.

As seen in Fig. 2, when the arch-blocks are placed side by side the flanges K come in contact with each other, while a space is left between the overhanging iianges J on the side of the arch-block. After the arch-blocks are thus placed the key Q is first inserted through a plurality of arch-blocks, and the concrete or cement is applied and fills the space above and between the arch-blocks, as well as the space between the lower face of the I-beam and the flanges G. The filling of concrete, cement, or other suitable fire-proofing material between the lower side of the beam and the upper faces of the flanges G not only affords protectiou to the beam in addition to the protection offered by said iianges, but it is evident that in the absence of such filling said flanges G could be easily broken or fractured. The filling completely fills this space between the beams and said anges G, and thereby forms a solid and rin backing and support for said ianges, which prevents the same from being easily fractured. In my application for patent iiled March 17, 1900, Serial No.- 9,028, I show a projection or fiange of an arch-block IOO so backed or supported, although a space, as shown in this application, does not exist between the same and the beam. The function of said filling is, however, present, and the result-namely, the backing and supporting of a flange or projection ot' an arch-block that extends below a beam and is not firmly backed and supported by said beamis the same. In this way it is seen that the beams M are effectually protected on all sides and that by reason of the keyway F and the flanges J and K a bond is provided that holds the archblocks in place and supports them under all conditions.

In Figs. 4to dan arch-block N is illustrated in which the base C and the uprightwalls D are dispensed with. Said arch-block N, how ever, is provided with a flange K' to meet and contact with a companion arch-block, also the base-flange G' and overhanging iiange H', the space between which receives the iange of the I-beam. The upper side of the arch-block is provided with a plurality of channels P, the walls between which are preferably flaring or dovetailed at their upper end, and at the upper end of the arch-block is a groove F', which, in connection with a corresponding groove of a companion arch-block, forms a keyway, as shown in Fig. 6, to receive the key Q', that extends through a plurality of arch-blocks, as will be understood. In this construction the cement or concrete protects the I-beam as before, while in connection with the key Q' it forms a bond to afford the requisite support.

I do not claim herein the specific construction of arch-block shown in Figs. 4t, 5, and 6, as the same forms the subject-matter of claims of a divisional application filed June 30, 1900,

-Serial No. 22,109.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

l. An arch-block for a fireproof construction having a base, an upper side, upright Walls or partitions joining the same, and an upright channel or keyway in the end of one of said-walls or partitions.

2. An arch-block for a iireproof construction consisting of a base, and an upper side piece, said base having laterally-extending fianges, and said upperside piece having laterally-extending flanges of less width than the iianges of the base.

3. An arch-block for ireproof construction consisting of a base having laterally and rearwardly extending fianges, and an upper side piece having laterally and rearwardly extending flanges of less width than the flanges of the base.

4. An arch-block for fireproof construction consisting of a base, an upper side, said base and upper side beingjoined at one end of the arch-block, and a plurality of longitudinal upright walls or partitions extending between said base and upper side.

5. In a fireproof construction, the combination of a beam having flanges, arch-blocks having over-hanging end lianges resting upon the flanges of said beam and provided at their ends with base-franges extending below the' flanges of said beam and adapted to meet the base-flange of an adjacent arch-block, lateral base-flanges upon said arch-blocks adapted to meet the lateral base-lianges of adjacent arch-blocks, said end base-tianges being situated below the flanges of the beam to provide a space, and a filling between said beams, upon and between said arch-blocks, and within the space between said fianges of the beam and the base-flanges of the arch-blocks.

6. In a fireproof construction, the combination with a beam having flanges, of archblocks, resting upon said flanges and provided with base-[langes extending below said beam and adapted to meet with the base-flanges of an adjacent arch, the upper faces of said baselianges being situated below the beam and having a space therebetween, said arch-blocks abutting each other below and separated from each other above, and a filling of concrete or cement within said space between the blocks and extending in said space below the beam.

7. In a fireproof construction, the combination with a beam having flanges, of archblocks having shoulders resting upon said extending below the said beam-flanges and .adapted to meet the base-flange of an adjacent arch-block, the upper faces of said baseanges being situated below the beam forming a chamber, a space being provided between the sides of adjacent arch-blocks above the beam-flanges,`and a filling in said space below said beam and resting partly upon said arch-blocks and the upper face of said beamfianges.

b. In a fireproof construction, the combination with arch-blocks suitably supported and meeting at their inner ends, grooves in the upper ends of said arch-blocks, a key eX- tending through the grooves of a plurality of arch-blocks, lateral iianges at the bases of said arch-blocks meeting lateral flanges of adjacent arch-blocks, said flanges being situated below the said keys, and a filling resting upon said arch-blocks and extending .beneath said keys.
